WHITE, OF SAME. PLACE. Lem" Patent o. 60,3'l8, dated December 11, 1866.

TO ALL wnoM rr MAY cononnu:

Be it known that I, R. B. Durrou, of Iron Hill, in the county ofJackson, and State of Iowa, have invented a new and useful Improvementin Sled Brake; and I do hereby declare that the following is a full,elem-,aud

exact description thereof, which will enable others skilled in theart tomake and use the same, reference being had to the accompanying drawings,forming part of this specification, in whichp a Figure 1 is a side viewof a sled, with cry-improved brake attached, a part of the'rave beingbroken away.

Figure 2 is a detail sectional view, taken through the line :1: x,fig. 1. Similar letters of reference indicate like parts. y p y 'Myinvention has for its object to furnish an improved brake for attachmentto sleds,, and it consists in the combination and arrangement of thejointed dog, clasp, lever, fulcrum-rod, ratchet-bar, and spring witheach other and with the rave and runner of the sled, as hereinafter morefully described.

A is the runner, B the knees, the beams, and D the rave of the sled,about the construction and arrlange ment of which parts there is nothingnew, E is the fulcrum-rod, which passes down through the rave D, and

has a screw formed upon its lower end, by means of which it is screwedinto the runner A. Upon the upper end of the rod E are formed 'ears, towhich the lever F is pivoted by a bolt passing through the said ,earsandlever, as shown in fig. 1. The lever F extendsback alittle beyond therear end of the rave;D,,and to its rear end is pivoted the upper endofthe dog G. To the sides of the rear'end of the runner A are attachedthe ends of a metallic strap or clasp H, which forms a socket for thereception of the dog G, as shown in fig. The ends of the clasp H shouldbe let into the sides of the runner A so that their outer surfaces maybe fl ushwit h the sides of the runner. The dog G is of such a lengththat when the forward end of the lever is raised the,

lower end of the said dog may project below the lower edge or face ofthe runner A, as shown in pfig 1. The dog G is also jointed, as shown atthe point g',so that the lower part of said dog may work vertically jnthe. clasp H, as it is operated by the lever F. I is a ratchet-bar,which is pivoted to earsJ, ,attachedto thejupp'er surface of the rave D.The lower end of the ratchet-bar I is made square, and when thesaidfbari is raisedthe said square end rests upon one end of the spring K,the other end of which is attached'toJthe rave 1),as'shown in fig. 1. Bythis construction the ratchet-bard may be turned down upon the upperside of the rave Dfwhen not in use, so as to be wholly out of the way.Upon the edge of the lever]? is formed a fiange f', whichj enters theteeth of theratchet-bar I and holds the lever F and dog G securely inany position in which they may be placed.

I claim as new, and desire to secure byLetters Patent- The combinationand arrangement of the jointed dog G, clasp H, lever F, fulcrum-rod E,ratchet-bowl, and spring Kwith each other, and with the rave D andrunner A of the sled,,the whole' being constructed and 1 operatedsubstantially as herein described, and for thepurpose set forth.
